M vl wmw WATER-SUPPLY SYSTEM FOR EXPLOSIVE-IENGINES.

Specification of Letters Patent.

Patented m. 2, 1917.

1 Application filed June 24, 1915. Serial No. 36,162.

Victoria, in the Province of British Columbia, Dominion of Canada, have invented certain new and useful Improvements in Watier-Supply Systems for Explosive-Engines; and I do hereby declare the iiollowing-to be a full, clear, and exact description ofthe invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to water supply systems for explosive engines, and is particularly adapted for use in connection with those engines in which the cooling system embodies a radiator.

The object of the invention resides in the provision of a system of the character named through the instrumentality of which water from a surplus supply may be delivered into the radiator as the supply in the radiator diminishes without the necessity. of stopping the vehicle with which the radiator is associated. 4

With the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularl pointed out in the appendedclaim.

In describing the invention in detail ref erence will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the sev eral views, and in which Figure 1 is a plan view showing the sys- 'tem associated with an automobile, the parts of the latter being sparsely disclosed for the sake of elearness; Fig. 2, a side view of what is shown in Fig. 1; Fig. 3, a section through the water supply tank, and Fig. 4,

a section through a fragment of the pipe leading from the air pump to the water sup ply. tank.

Referring to the drawings 10 indicates the radiator of a motor vehicle and 11 the water supply tank of my improved system. This tank is preferably mounted under the rear seat of the motor vehicle for the sake of convenience. Leading from the bottom of the tank 11 and communicating with the interior of the latter is a pipe 12. The end of the pipe 12 remote from the tank 11 is in communication with the radiator 10. The tank .11 is provided with an opening 11 in its top and threaded in this opening is a hollow plug 12 having an opening 13' in its top. Secured in the opening 13 in communication with the interior of the plug 12 is a tubular member 14. The bore of this member 1 1 is so shaped as to form a valve seat 15' with which cooperates a valve 15. Threaded on the top of the member 14: is a cap 16 having an opening 17 in its top. The upper end of the valve 15 is reduced to form a shoulder 18 so that when the cap 16 is screwed home the reduced portion of the valve passes through the opening 17 and the top of the cap cooperates with the shoulder 18 to force the valve 15 to its seat. By removing the cap 16 the valve 15 can be manually removed and a flexible tube engaged over the member 14 for the purpose of filling the tank 11 by siphoning. Mounted on the motor vehicle in a position convenient for operation by the driver is an air pump 13 which is connected by a pipe 14 with the interior of the plug 12 for the purpose of supplying air to the interior of the tank 11 toforce water from the tank through the pipe 12 into the radiator 10.

What is claimed is In a system of the class described, the combination of a radiator, a water supply tank, a pipe connecting the radiator and tank, a hollow plug threaded in an opening in the top of the tank, a tubular member secured to the top of the plug and in communication with the interior of the latter, said member having its bore shaped to form a valve seat, a valve cooperating with said seat and having a reduced upper end forming a shoulder, a cap threaded on the upper end of the member and having an opening in its top through which the reduced end of the valve is adapted to work and whereby.

the top of the cap will cooperate with the shoulder on the valve to force the latter to its seat when the cap is screwed home, an air pump, and a pipe connecting the pump with the interior of the plug.

In testimony whereof, I aflix my signature, in the presence of two witnesses.
